To all whom it mq/g/ concern:

l rod 22 is disposedcoaxially withthecasing 9,

Be it known thatl, WALTER LAMBERT, a j and mounted rigidly upon this slide rod 1s a A lcitiz of the United States, and a resident .of Sunn side,'in. the county of Yakima and State o WVashington, have invented a new and VImprovedElec'tric Pum of which the full, clear, an 1 exact descrip- 'tion.

My invention relates to pumping mechan- Iism,and morepart-icularly to electric. machinery used `for actuating a pump. 1

My mventionfurther relatesto means for automatically throwing both the pump and the electric mechanism out ofaction when the water in thetank reaches a predetermined 'Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters Aof reference indicate corresponding parts in all the '(fures.

Y Figure 1 is a diagrammatic s ide elevation l showing the general'arrangemcnt 'of the A mounting the same, ther contact mechanism pump and the electric mechanism, together with thetank, a portion of which is removed; Fi f. 2.is a central vertical section through the so enoid and certain Aparts .connected therewith, showing'the movable core, lneans for and the electrical connections for the latter:` Fig. 3 isan enlarged side elevation showing lar ec section u on the line 4--4'ol` Fig. 2,

loo ing in the 4irection of the arrow, 'and showingthecontact rocking lever and its accompanying' parts for opening and closing Y tlie-circuit;and Fig. 5 is a fragmentary plan view of one of the adjusting collars for controlling the stroke of thel solenoid core, and showing also the means for adjusting this collar..v j A dynamo is shown at 6, a reciprocating pump at 7,1a water tankat 8, and a solenoid casing at 9. TheV water supply comes throughthe pipe 10 and is passed by the pump 7 through pipes 11, 12 and 13 into the j tank8. Mounted within the upper portion of this tank is a oat 14 secured to acontact 4leven-.15. -Normallyengaging the outer or free, end ofjgbis lever is a contact point 16, and 'coimectedwith the latter is a wire 17. Tliis wireleads'to afuse 19-Which is connected' by a wire 20 with a binding post 20a. Awire"21 4is connected'with another binding post 2 1*t and with theA dynamo 6.

equivalent wearing surfaces, whereby the collars are prevented romundue wear and abrasion. Stirrups 23, 29 are integral with" the collars 24, .25, and are provided with cyllindrical barrels`30, 31 having pins 32, 33, 34

mounted therein for the purpose of holding the barrels 31 in definite predetermined positions upon the guide rod. 'The latter is provided With holes 35, 36, the holes Z5-being dis osed intermediate of the holes36 and in Fig. 5. The purpose of this arrangement is tween the barrels 31 and the guide rod-22. lBy removing the pins the relative position of thebarrels to eachother and to the guide rod ZZfmay be changed at will. "In this way the4 Vadjusting collars 24, may be spaced at pre-- determined distances from 'each other for the purpose of regulating the stroke oi the core 23;"and the guide rod 22. A cylinder l37 of non-magnetic material, preferablyl brass, serves as a spool body and is mounted sta- Encircling the cylinder 37 is a sheet 38 of insulating' material, .and encircling this is a winding 39.- Similarly another cylinder 4() is provided with'. a sheet 41 of insulating material, and encircling this is a win ding 42. The cylinder 40 is cylin er 37 having a similar heads 43 and 44 are connected by .a metallic a iiierent plane asA will be understoodffrom rovided with a circular head 43, the

When the contact arm is rocked back and forth it successively makes and breaks contact with each of the contact points 48 and 49. Another bridge 50 connects together the heads 43', 44.
